CLOD-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 465,356, dated January5, 1 892.\ Application led December 11, 1890. Serial No. 374,274. (Nomodel.)

To all whom t may concern,.-

Be it'known that I, FREDERICK MEIER, a

citizen of the United States, residing'at Battle Creek, in the county ofCalhoun and State of Michigan,

have invented certain Vnew and useful Improvements inLand Lump and OlodyCrushers, of which the following is a specifi' cation, reference beinghad to the accom panying drawings, forming part thereof.V

The object of this invention and vmode of vits operation will bereadilydiscovered by; those skilled in land cultivation by a'mere 'inspectionof the drawings.

that, among its objects are the following: fi rst, to out the hard clodsand lumps of baked soil to pieces instead of simply crushing the same,as heretofore attempted, by the mere weight of the implement; second, tolet the severed parts pass between the cutter-bars to the'interior ofthe roller-cylinder, where theyare alternately lifted and let fall frombottom to top, and vice versa, of the rollerlby means of centrallyconverging clods are Carried and thoroughly pulverized, as is evident.

In the drawings, Figure l represents a front View of my novel inventionhaving the tonguev .the roller-heads with all the bars in place.

Fig.- 4 represents the completed implement in perspectiveelevation,mounted and ready for Fig. 5 is a longitudinal section throughone of the roller-heads, show ing one construction by which the bars-maybe removed independently the one of the other; and Figs' and 7 arerespectively an inner face View and an outer face View of theroller-head, and shows another construction adapted to permitindependent removability of the bars. l l l Referring now particular] yto the letters and numerals of reference designating different portionsof the drawings, wherein similar letters and iigures referto the sameparts in all the views. y A is a platforminclosedbyanupwardly-projecting border A', which forms a con ven- Further thanplates suitably prov vided therein, whereby the severed lumpsandY stonesor other obstructions from the field,

'and also kfor use in weighting the implement -according to theever-varying conditions of soil, dac'. Depending vertically from theextreme ends of theplatforln or from its border A are theroller-supports and bearings 1 l, andcentr'ally between the sainedepends a similar support?, and from the said platform (or the tongue)rises the usual support for the drivers seat a, and diagonal lateralbraces c c attach at their rear ends to the platform, and at theirforward ends are firmly fixed to the tongue T, and asimilar brace (lreaches from the under side of said tongue to the'central verticalsupport 2, as seen in Figs. 1,2, and 4. B is the roller-shaft, which maybe made in two parts, so that the rollers, of which two are 'preferablyused, revolve independently, or the said shaft may be continuousthroughout, as maybe preferred.

- C represents the roller-head, provided on its inner annular face withanges l), b', and Z1,

6oL I arranged V in series, as shown, said flanges b and b incliningtoward each other, thus forming receptacles in shape similar to atruncated cone, the'base of eachbeing formed by the fiange b and thesides by the flanges b and bto receive the ends of the bars D, whichareV triangular or V-shaped in cross-section, and are secured totheheads by means of setscrews S engaging with suitable countersinks orholes in the base of said bars. The bars are removable independentlythe'one of the other without removing or displacing the roller-heads.Many constructions to permit of such removability of the bars willreadily suggest themselves to those skilled in the art towhich thisinvention appertains, and I therefore do not wish to be understood aslimitinginyself to any particular construction for the purpose. Twoexamples are shown in the drawings.

In Fig. 5 the bars are shown as made somewhat shorter than the spacebetween the heads, so that they will have an endwise movement betweensaid heads when the bolts holding them are loosened of a little morethan the amount of projection inward of a liange,

so that by simply loosening the bolts holding a bar and moving said baruntil one'end is in Contact with the inner surface of a head the IOOopposite end is free to drop down out of engagement with the flange,when the bar cank be removed.

In the construction shown in Figs. (i and 7 the heads are or may besolid and the ends of the bars reach through the same to theontermostfaces thereof. With this construction by simply turning backthe set-screws at either end or head the bar will be permitted to slidein its V-shaped horizontal channel, so as to allow of its removal.Plates P are provided reaching from the base of two or more of thecutter-bars D, say, about one-half way therefrom toward the centralshaft, the office of which is to alternately lift and let fall the hardlumps of soil that pass between the cutter-bars to the inside of theroller. These plates may be attached to the heads or to the base of saidbars, or to both, so that they be firmly fixed and run longitudinally ofsaid roller, whereby a much more perfect pulverization and commutationof the soilis secured than by any means heretofore employed, as isevident. I prefer to have the openings between the cutter-bars aggregateabout one-quarteror one-third. the entire periphery of the roller at thebase of said bars, though this is a matter of no great moment, providedconsiderable openings are provided between each of the longitudinal barsfor the entrance of the severed lumps and exit of the pnlverized soil.

Having thus fully described and illustrated my invention, and pointedont its more distingnishing features and novel mode of operation, what Iclaim, and desire to secure by Letters Patent of the United States, is-

1. In a land-roller, the periphery thereof, formed of cutter-bars andopen spaces between the same communicating with the interor of theroller, said bars having holes or countersinks in their bases, andset-screws engaging said holes or conntersinks for re movably securingthe bars in place, substantially as described. I

2. In a land-roller, the roller-heads, in combination withindependently-removable cutter-bars and set-screws engaging saidcutterbars and serving to hold the same rigidly in the place described.

3. In a land-roller, the periphery thereof, consisting of alternatelongitudinal cutterbars and open spaces between the same communicatingwith the interior of said roller, in combination with longitudinalplates within the roller, all substantially as described, and for thepurpose specified.

4. In a land-roller, the periphery thereof, formed of cutter-bars andopen spaces between the same, said cutter-bars having broad bases orrear ends and tapered therefrom to a point and formed in their rear endswith t holes or conntersinks, in combination with set-screws engagingsaid holes or conntersinks and securing said cutter-bars rigidly inplace, but permitting their removal, as speciiied.

5. In a land-roller, the periphery thereof, consisting of alternatelongitudinal cutterbars and spaces between the same communieating withthe interior of said roller, longitudinal plates reaching the length ofsaid bars and depending therefrom, but about half the distance from thebase of said bars to the roller-shaft, and set-screws s, and flanges b bb, arranged in series, as shown, for the purposes set forth.

In testimony whereof I hereunto affix my hand and signature, this 31stday of October, A. D. 1890, in the presence of two attesting witnesses.

FREDK. MEIER.
